Balalaika (バラライカ) is the 2nd single by Tsukishima Kirari staring Kusumi Koharu (Morning Musume). It was released on October 25, 2006 in both limited and regular editions. The limited edition came with a Super Corabo Mirufii card. The limited and first press release of the regular came with a special sticker.

The Single V was released on November 8, 2006. It sold 7,720 copies and peaked at #6 on the Oricon charts.

Balalaika was used as the 2nd opening for the anime Kirarin☆Revolution, and Mizuiro Melody was used as the 3rd ending theme for the same anime.

The song was turned into a parody song "Yararaika" that went viral. Yuichiro Nagashima, the cosplay kickboxer, once entered the ring in Abe's eponymous jumpsuit with the parody song as background music.
